CART-19 T Cells
The subject's thawed T cells will be modified in one or two different ways that will allow the cells to identify and kill the tumor cells (B cells). The T cells will be infused over 10-15 minutes on days Days 0, and 1. Day 14 is tentative based on response. CART-19: Day 0: 10% of total dose Day 1: 30% of total dose if patient is stable (no significant toxicity) from prior dose.
